Emit Mode| ifnotsolid – Specifies the way the objects in the Emitter Nodes emit fluid.
Surface Force – The surface of the emitters will eject the selected fluid channels along the geometry normals. In this mode, the discharge is named Outgoing Velocity and it specifies the speed of the emitted fluid in units/sec. The displayed units will change accordingly if the scene units change.
This mode can work with both Solid and non-Solid emitters. If you use a Mask for the discharge in Surface Force mode, white areas of the emitter's surface will eject fast fluid, while darker ones would emit more slowly. Black areas will not emit at all.
Volume Brush – The fluid inside the volume of the emitters will gradually change towards the selected channel values. When this mode is selected, the discharge is named Brush Effect (%) and it specifies the rate at which the transition takes place. When Brush Effect is 100%, the fluid will immediately reach the selected channel values, and if Brush Effect is less, it specifies how close the fluid values will get to the values from the Source over 1 second. E.g. if the Temperature inside an emitter's volume is 1000 and the Source emits Temperature 2000 with Brush Effect of 80%, then after 1 second the temperature will have risen to 1800. This mode is useful for creating standing volumes of fluid with a high Brush Effect, or alternatively - to slowly convert the fluid inside the volume of the emitters to the values selected below over a period of time. Note that you can both increase or decrease the values of the fluid channels in Volume Brush mode. WhenBrush Effect (%) is 0, then the Source has no effect.
This mode requires that all selected emitters are set into non-Solid mode from their Per-Node Properties. If you use a Mask for the discharge in Volume Brush mode, white zones in the volume will have the Brush Effect you have specified, while darker zones will use a smaller Brush Effect. Completely back zones in the mask would not be affected at all by this Source.
Volume Inject – The volume of the emitters will discharge the selected fluid channels with added pressure. When this mode is selected, the discharge is named Inject Power and it specifies the added volume of the injected fluid per second.This mode is useful for getting explosive discharge. Inject Power can be negative, in which case the Source will suck in and delete the fluid.
This mode requires that all selected emitters are set into non-Solid mode from their Per-Node Properties. If you use a Mask for the discharge in Volume Inject mode, white zones in the volume will have the Inject Power you have specified, while darker zones will use a smaller Inject Power. Completely back zones in the mask would not be affected at all by this Source.

info
When emitting from particles in any of the 'Sphere' Prt Shape modes, the Surface Force Emit Mode is not supported - Phoenix will automatically fall back to Volume Inject mode. Only Use Particle Shape supports all 3 emit modes.
Inject Power / Brush Effect (%) / Outgoing Velocity | discharge / brusheffect / outvel – These parameters control the strength of the source. Check Emit Mode for more info.
Mask |dmap, usedmap – Allows you to vary the Outgoing Velocity, Inject Power or Brush Effect (%)over the surface or the volume of the emitters. White areas of this map will have the strongest discharge, while black areas of the map will not discharge at all. The individual fluid channels can also be modulated using dedicated maps from the options below. See the info on the Emit Mode option above for more info on how the Mask affects each mode.
Modifiers|dmoddisch – Discharge Modifiers can be attached here in order to affect the Outgoing Velocity, Inject Power or Brush Effect (%) parameters.
Noise | noise – Varies the Outgoing Velocity, Inject Power and Brush Effect (%) across the surface or the volume of the emitting geometry or particle. The variation also changes over time. This is a shorthand for using an animated noise in the Mask slot.

Emit Liquid – Enables or disables liquid emission. Disabling this option is useful in situations where only foam and splashes need to be emitted but not the liquid itself.
RGB | uvw, useuvw – If the RGB Map is not enabled, the emitted fluid's RGB channel will contain the specified color. If the RGB Map is enabled, the RGB values from the texture map will be used instead of the color swatch. If the RGB channel is not enabled in the Output rollout of the Simulator, this parameter will be ignored. Also, note that if Emit Mode is set to Volume Brush or Volume Injectandthe Map uses Explicit Map Channel or Vertex Color Channel mapping, then the Map will be applied on the whole volume, based on the closest geometry surface.
Modifiers |dmodrgb – A discharge modifier can be attached here in order to affect the RGB parameter.
Map |uvwmap, useuvwmap– Allows you to vary the RGB over the surface or the volume of the emitters. If this is not used, the Source will emit equal RGB over the entire surface or volume of the emitters.
None – The RGB channel will not vary. Texmap – Allows you to specify a texture map to color the fluid emitted by the Source. If this is used, the color swatch is ignored and the RGB comes entirely from the texture. Vertex Color – The RGB channel of the emitted fluid is determined by the emitter node's vertex colors. If this is used, the color swatch is ignored and the RGB comes entirely from the vertex color. The texture map slot is also ignored.

tip
To render these RGB colors for smoke, set the Smoke ColorBased On parameter to RGB.
For rendering of meshed liquids, set a Grid Texture as the Diffuse map for a Standard or V-Ray Material, and set the Grid texture's Channel to RGB.
